Media guidelines
Paper guidelines
Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample
of the paper or specialty media before buying large quantities.
Paper characteristics
The following paper characteristics aect print quality and reliability. Consider these characteristics when
evaluating new paper stock.
General information

Page 30
4514-6xx
Weight
The printer trays can automatically feed paper weights up to 120‑g/m2 (32‑lb) bond grain long paper. The
multipurpose feeder can automatically feed paper weights up to 163‑g/m
2
lighter than 60 g/m

75‑g/m
(20‑lb) bond grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), we recommended
to use 90 g/m
(16 lb) might not be sti enough to feed properly, causing jams. For best performance, use

(24 lb) or heavier paper.
2
(43‑lb) bond grain long paper. Paper
Note: Two‑sided printing is supported only for 60–90‑g/m
2
(16–24‑lb) bond paper.
Curl
Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can
occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper
unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to
printing and can cause feeding problems.
Smoothness
Paper smoothness directly aects print quality. If paper is too rough, then toner cannot fuse to it properly. If
paper is too smooth, then it can cause paper feeding or print quality issues. Always use paper between 100
and 300 Sheeld points; however, smoothness between 150 and 250 Sheeld points produces the best print
quality.
Moisture content
The amount of moisture in paper aects both print quality and the ability of the printer to feed the paper correctly.
Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes
that can degrade its performance.
Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing.
Extend the time to several days if the storage or transportation environment is very dierent from the printer
environment. Thick paper may also require a longer conditioning period.
Grain direction
Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length
of the paper, or grain short, running the width of the paper.
2
For 60–90‑g/m
(16–24‑lb) bond paper, grain long paper is recommended.
Fiber content
Most high‑quality xerographic paper is made from 100% chemically treated pulped wood. This content provides
the paper with a high degree of stability resulting in fewer paper feeding problems and better print quality.
Paper containing fibers such as cotton can negatively aect paper handling.
Unacceptable paper
The following paper types are not recommended for use with the printer:
• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers,
carbonless copy paper (CCP), or no carbon required (NCR) paper
• Preprinted papers with chemicals that may contaminate the printer
• Preprinted papers that can be aected by the temperature in the printer fuser
General information
30
Page 31
4514-6xx
• Preprinted papers that require a registration (the precise print location on the page) greater or lesser than
+/‑2.5 mm (+/‑0.10 inch), such as optical character recognition (OCR) forms
In some cases, registration can be adjusted with a software application to successfully print on these forms:
• Coated papers (erasable bond), synthetic papers, thermal papers
• Rough‑edged, rough or heavily textured surface papers, or curled papers
• Recycled papers that fail EN12281:2002 (European)
• Paper weighing less than 60 g/m
2
(16 lb)
• Multiple‑part forms or documents
Selecting paper
Using the appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid paper jams and poor print quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is usually
indicated on the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same tray; mixing results in jams.
• Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
• Use grain long for 60 to 90 g/m
• Use only forms and letterhead printed using an
2
(16 to 24 lb) weight paper.
lithographic or engraved printing process.
oset
• Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to
withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. Use inks that
are not aected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements;
latex inks might not. When in doubt, contact the paper supplier.
Preprinted papers such as letterhead must be able to withstand temperatures up to 230°C (446°F) without
melting or releasing hazardous emissions.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent.
Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative
humidity between 40 and 60 percent.
• Store paper in cartons, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
• Do not store anything on top of individual paper packages.
• Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and
wrapper help keep the paper clean, dry, and flat.

Using recycled paper and other oce papers
As an environmentally conscious company, Lexmark supports the use of recycled oce paper produced
specifically for use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US government
a study demonstrating that recycled paper produced by major mills in the US fed as well as non-recycled paper.
However, no blanket statement can be made that all recycled paper will feed well.
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of
test paper from around the world, using chamber tests for dierent temperature and humidity conditions.
Lexmark has found no reason to discourage the use of today's recycled oce papers, but generally the following
property guidelines apply to recycled paper.
• Low moisture content (4–5%)
• Suitable smoothness (100–200
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheeld units) and
much rougher papers (such as premium cotton papers, 200–300

• Sucient bending resistance in the direction of feed
Recycled paper, paper of lower weight (<60 g/m
paper that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is
required for reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing,
consult your paper supplier. Remember that these are general guidelines only and that paper meeting these
guidelines may still cause paper feeding problems in any laser printer (for example, if the paper curls excessively
under normal printing conditions).

Using specialty media
Tips on using card stock
Card stock is heavy, single‑ply specialty media. Many of its variable characteristics, such as moisture content,
thickness, and texture, can significantly impact print quality. Print samples on the card stock being considered
for use before buying large quantities.
When printing on card stock:
• Make sure the Paper Type is Card Stock.
• Select the appropriate Paper Texture setting.
• Be aware that preprinting, perforation, and creasing may significantly aect the print quality and cause jams
or other paper handling problems.
• Check with the manufacturer or vendor to ensure that the card stock can withstand temperatures up to
240°C (464°F) without releasing hazardous emissions.
• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi‑liquid and volatile components into the printer.
• Use grain short card stock when possible.

Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed
that the envelopes can withstand temperatures up to 230°C (446°F) without sealing, wrinkling, curling
excessively, or releasing hazardous emissions.
specifically
• For best performance, use envelopes made from 90‑g/m
envelopes must not exceed 70‑g/m
• Use only new envelopes from undamaged packages.
• To optimize performance and minimize jams, do not use envelopes that:
– Have excessive curl or twist
– Are stuck together or damaged in any way
– Have windows, holes, perforations, cutouts, or embossing
– Have metal clasps, string ties, or folding bars
– Have an interlocking design
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed or closed position
– Have bent corners
– Have rough, cockle, or laid finishes
• Adjust the width guides to fit the width of the envelopes.

Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note: Use only paper label sheets. Vinyl, pharmacy, and two‑sided labels are not supported.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide available
at
http://support.lexmark.com.
When printing on labels:
• Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
– The labels can withstand temperatures up to 240°C (464°F) without sealing, excessive curling, wrinkling,
or releasing hazardous emissions.
– Label adhesives, face sheet (printable stock), and topcoats can withstand up to 172‑kPa (25‑psi) pressure
without delaminating, oozing around the edges, or releasing hazardous fumes.
• Do not use labels with slick backing material.
• Use full label sheets. Partial sheets may cause labels to peel o during printing, resulting in a jam. Partial
sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and toner
cartridge warranties.
• Do not use labels with exposed adhesive.
• Do not print within 1 mm (0.04 inch) of the edge of the label, of the perforations, or between die‑cuts of the
label.
General information
33
Page 34
4514-6xx
• Make sure the adhesive backing does not reach to the edge of the sheet. Zone coating of the adhesive
should be at least 1 mm (0.04 inch) away from edges. Adhesive material contaminates the printer and could
void the warranty.
• If zone coating of the adhesive is not possible, then remove a 2‑mm (0.08‑inch) strip on the leading and
driver edge, and then use a non‑oozing adhesive.
• Portrait orientation is recommended, especially when printing bar codes.
Tips on using transparencies
• Print a test page on the transparencies being considered for use before buying large quantities.
• Feed transparencies from the standard tray, or the multipurpose feeder.
• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand
temperatures up to 185°C (365°F) without melting, discoloring, osetting, or releasing hazardous emissions.
Note: If the transparency weight is set to Heavy and the transparency texture is set to Rough in the Paper
menu, then transparencies can be printed at a temperature up to 195°C (383°F).
• Avoid getting fingerprints on the transparencies to prevent print quality problems.
• Before loading transparencies, flex, fan, and straighten the stack to prevent sheets from sticking together.

Troubleshooting overview
Performing the initial troubleshooting check
Before you start the troubleshooting procedures, perform the following checks:
• Use genuine Lexmark supplies and parts for the best results. Third-party supplies or parts may aect the
performance, reliability, or life of the printer and its imaging components.
• With the power cord unplugged from the electrical outlet, check that the cord is free from the breakage,
short circuits, disconnected wires, or incorrect connections.
• Make sure the printer is properly grounded. Check the power cord ground terminal.
• Make sure the power supply line voltage is within 10% of the rated line voltage.
• Make sure the machine is securely installed on a level surface in a well‑ventilated area.
• Make sure the room temperature is between 16 and 32°C (60 and 90°F) and that the relative humidity is
between 8 and 80%.
• Avoid sites generating ammonia gas, high temperature, high humidity (near water faucets, kettles,
humidifiers), cold spaces, near open flames, and dusty areas.
• Avoid sites exposed to direct sunlight.
• Make sure the paper is the recommended paper for this printer.
• Make a trial print with paper from a newly opened package, and check the result.

If no error code is displayed, but a symptom is present, go to
“Base printer symptoms” on page 165.
Fixing print quality issues
The symptoms described in this chapter might require replacement of one or more CRUs (Customer
Replaceable Units) designated as supplies or maintenance items, which are the responsibility of the customer.
With the customer's permission, you might need to install a toner cartridge.
Initial print quality check
Before troubleshooting specific print problems, complete the following initial print quality check:
• Use only genuine Lexmark supplies. Third-party supplies may cause print quality problems.
• The printer must be in a location that follows the recommended operating environment specifications.
See
“Operating environment” on page 357.
• Check the life status of all supplies. Any supply that is low should be replaced.
• Load 20‑lb plain letter or A4 paper. Make sure the paper guides are properly set and locked. From the
control panel, set the paper size and type to match the paper loaded in the tray.
• Print a menu settings page. Be sure to keep the original menu settings page to restore the customer’s
custom settings if needed.
• Verify on the menu settings page if the following are set to their default values:
– Print resolution: 600 dpi
– Toner darkness: 8
• Check the transfer roll for damage. Replace if damaged.
• Check the toner cartridge and imaging unit for damage. Replace if damaged.
• Print the print quality pages to see if the problem remains. Use Tray 1 to test print quality problems.
• Print a print quality test page, and then look for variations in the print from what is expected. Verify if the
settings under EP Setup are set to their default values. See
Diagnostics and troubleshooting
“EP Defaults” on page 186.

Paper jams
Avoiding jams
Load paper properly
•
Make sure that the paper lies flat in the tray.
• Do not remove a tray while the printer is printing.
• Do not load a tray while the printer is printing. Load it before printing, or wait for a prompt to load it.
• Do not load too much paper. Make sure that the stack height is below the maximum paper fill indicator.
• Do not slide paper into the tray. Load paper as shown in the illustration.
• Make sure that the paper guides are properly positioned.
• Push the tray firmly into the printer after loading paper.
Use recommended paper
•
Use only recommended paper or specialty media.
• Do not load wrinkled, creased, damp, bent, or curled paper.
• Flex, fan, and straighten paper before loading it.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, weights, or types in the same tray.

• Make sure that the paper size and type are set correctly on the Embedded Web Server or the computer.
Note: Depending on your operating system, access the Paper menu using Local Printer Settings Utility or
Printer Settings.
• Store paper according to manufacturer recommendations.
Understanding jam messages and locations
When a jam occurs, a message indicating the jam location and information to clear the jam appears on the
printer display. Open the doors, covers, and trays indicated on the display to remove the jam.
Notes:
• When Jam Assist is set to On, the printer automatically flushes blank pages or pages with partial prints to
the standard bin after a jammed page has been cleared. Check your printed output stack for discarded
pages.
• When Jam Recovery is set to On or Auto, the printer reprints jammed pages. However, the Auto setting
does not guarantee that the page will print.
